Lemon Garlic Pasta
This Lemon Garlic Pasta is a bright, satisfying weeknight staple that comes together in under 30 minutes using simple pantry ingredients. Golden sautéed garlic, fragrant extra virgin olive oil, zippy lemon zest, and a generous shower of Parmigiano Reggiano create a silky, restaurant-worthy sauce with minimal effort. Naturally vegetarian and endlessly customizable, it's the kind of effortless dish you'll come back to every week.
Equipment
- Large pot For boiling pasta — at least 5-6 quart capacity
- Large stainless steel skillet or sauté pan 10–12 inch
- Microplane zester or box grater For zesting lemon and grating Parmesan
- Colander
- Tongs
- Ladle or measuring cup For scooping pasta water
- Cutting board and knife
Ingredients
- 12 oz spaghetti or linguine 340g
- 6 garlic cloves thinly sliced
- 1/3 cup extra virgin olive oil about 80ml; use the best quality you can find
- 1 lemon, zested and juiced about 3 tablespoons / 45ml juice
- 1/2 tsp red pepper flakes optional, for heat
- 1/2 cup freshly grated Parmigiano Reggiano about 50g; plus more for serving
- 1/2 cup reserved pasta water about 120ml; set aside before draining
- 1/4 cup fresh flat-leaf parsley roughly chopped
- salt and black pepper to taste
For serving
- extra virgin olive oil drizzle to finish
- Parmigiano Reggiano freshly grated, extra for topping
- red pepper flakes optional pinch to garnish
- lemon zest extra twist to finish
Instructions
- Fill a large pot with 4–5 quarts of water and bring to a vigorous boil over high heat. Salt generously — the water should taste like mild seawater.
- Add the spaghetti or linguine and stir immediately. Cook 1–2 minutes less than package directions for al dente. Before draining, scoop out at least 1 cup of pasta water and set aside, then drain the pasta.
- Add the olive oil and sliced garlic to a cold large skillet, then place over medium-low heat. Cook, stirring occasionally, for 4–5 minutes until the garlic is pale golden and fragrant — do not let it brown. If using, add the red pepper flakes and stir for 30 seconds.
- Reduce heat to low. Add the lemon juice (it will sizzle), then the lemon zest. Stir and let simmer gently for 30 seconds to infuse.
- Add the drained pasta to the skillet and toss with tongs to coat. Add 1/4 cup of pasta water and continue tossing vigorously, adding more pasta water a few tablespoons at a time until the pasta is glossy and lightly sauced.
- Remove the skillet from heat and sprinkle over the Parmigiano Reggiano, tossing quickly and continuously so the cheese melts smoothly into the sauce. Splash in a little more pasta water if it looks too thick.
- Season with salt and black pepper, toss in the fresh parsley, and plate immediately into warm bowls. Finish with a drizzle of olive oil, extra Parmesan, a pinch of red pepper flakes, and a twist of lemon zest.
Notes
Use fresh lemon juice only — bottled lemon lacks the bright, clean flavor this dish relies on. Zest before juicing for easier prep.
Don't skip the pasta water — the starch is the emulsifier that binds oil, cheese, and lemon into a cohesive, glossy sauce.
Keep heat low when making the garlic oil. Burnt garlic will make the entire dish bitter and there's no recovery.
Cook pasta al dente (1–2 min under package time) — it finishes in the skillet and will soften further.
Always grate your own Parmesan. Pre-shredded cheese contains anti-caking agents that prevent smooth melting.
Add the Parmesan off the heat — this prevents it from clumping and ensures a creamy, even coating.
To make it vegan, replace Parmesan with 2–3 tablespoons of nutritional yeast and a little extra olive oil.
Customize with add-ins: sautéed shrimp, sliced chicken, asparagus, baby spinach, or burst cherry tomatoes all work beautifully.
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in a skillet with a splash of water and olive oil. Do not freeze.
This dish is best served immediately — it stiffens as it sits and does not hold well.
